Answer:
y = - 2.5
Step-by-step explanation:
Given
0.5y = - 1.25 ( divide both sides by 0.5 )
y = [tex]\frac{-1.25}{0.5}[/tex] = - 2.5
Answer:
y=-2.5
Step-by-step explanation:
0.5/0.5 y=-1.25/0.5

A number decreased by 33 is the same as 51 minus 5 times the number.
The equation is
Your answer is [tex]x-33=51-5*x[/tex].
A number --> x
Decreased by 33 --> -33
Is the same as 51 --> =51
Minus 5 --> -5
Times --> *
The number --> x
All together it is x-33=51-5*x.

find the distance
(-2, 1) and (4,3)
Answer:
[tex]2\sqrt{10}[/tex] units
Step-by-step explanation:
The distance formula states that [tex]D(x_{1} ,y_{1})(x_{2},y_{2} )=\sqrt{(x_{2} } -x_{1} )^2+(y_{2}-y_{1} )^2\\[/tex].
We then plug in our points and compute.[tex]\sqrt{(4-(-2))^2+(3-1)^2} =\sqrt{6^2+2^2} =\sqrt{36+4} =\sqrt{40} =\sqrt{2^2*2*5} =2*\sqrt{2*5} =2\sqrt{10}[/tex]
The * represents multiplication.

The triangle shown will be rotated 90° clockwise about the origin. What are the new coordinates of point B? A) (2, -4) B) (2, 4) C) (4, -2) D) (-4, -2)
Step-by-step explanation:
Hey there!
Your required answer is option B.
Reason: The coordinates of B is (2,4).
The formula for rotating the coordinates 90° clockwise is; (x,y)------(y,-x).
So, using this formula we get;
Answer; (4,-2).
Hope it helps...
The new coordinates of point B are (4,-2). So, option C is correct.
Important information:
The graph of the triangle ABC is given.The triangle will be rotated 90° clockwise about the origin.Rotation:From the given graph, it is clear that the coordinates of point B are (2,4).
If a figure is rotated 90° clockwise about the origin, then
[tex](x,y)\to (y,-x)[/tex]
Using the above rule, we get
[tex]B(2,4)\to B'(4,-2)[/tex]
Therefore, the option C is correct.

Why can you write a subtraction problem as an addition problem?
First, keep the first number (known as the minuend). Second, change the operation from subtraction to addition. Third, get the opposite sign of the second number (known as the subtrahend) Finally, proceed with the regular addition of integers. Proceed with the regular addition of the integers.
⊗ Note that you will eventually add integers. So for your convenience, here’s the quick summary of the rules on how to add integers.
Adding two integers having the same sign Add their absolute values then keep the common sign. Adding two integers with different signs
Subtract their absolute values (larger absolute value minus smaller absolute value) then take the sign of the number with the larger absolute value.
You'll need to transform the problem from subtraction to addition. To do that, we keep the first number which is –13 , change the operation from subtraction to addition, then switch the sign of + 4 to –4. The final step is to proceed with regular addition. Add their absolute values. Then we determine the sign of the final answer. Since we are adding integers with the same sign, we will keep the common sign which in this case is negative. Just like before, convert a subtraction problem to an addition problem. Positive 9 remains, switch the operation from “minus” to “plus” then get the opposite sign of the subtrahend (second number) from negative to positive.
Now, let’s add them. We are adding two positive integers so we expect the answer to be positive as well because the common sign is positive. I hope you are already getting the hang of it. Let’s make this an addition of integers problem first then proceed with regular addition of integers with different signs.
So we subtract their absolute values first then get the sign of the number with larger absolute value.
Subtracting the absolute values, we have 24 minus 19 which gives us +5. But the final answer is – 5 because the sign comes from –24.

needa know which one is irrational
Answer:
√2
Step-by-step explanation:
For a number to be "irrational", you cannot turn it into a fraction.
2 = 2/1
√4 = 2/1
2^2=4/1
√2 = 1.41421356237
See which one is not a fraction?
That would be your answer because it is irrational

Determine if 0.71875 is rational or irrational and give a reason for your answer.
Answer:
Rational number
Step-by-step explanation:
Given
[tex]Digit = 0.71875[/tex]
Required
Determine if it is rational or not
[tex]Digit = 0.71875[/tex]
Convert to fraction
[tex]Digit = \frac{71875}{100000}[/tex]
Divide numerator and denominator by 25
[tex]Digit = \frac{2875}{4000}[/tex]
Divide numerator and denominator by 25
[tex]Digit = \frac{115}{160}[/tex]
Divide numerator and denominator by 5
[tex]Digit = \frac{23}{32}[/tex]
The above is a rational number because it can be expressed as a fraction of two integers
